ELECTRICALLY-OPERATED WALL-PAPER MACHINE.

Application filed January 23, 1928. Serial No. 248,831.

This invention relates to a wall paper handling machine, the generaobject of the invention being to provide means for unrolling the paper,applying paste to the under side thereof and for trimming the edges ofthe paper as it is being unrolled.

. further object of the invention is to provide a conveyor on which theunrolled and pasted paper hes, so that it. can be easily picked up bythe paperhanger.

A still further object of the invention is to provide adjustable cuttingmeans for reducing the width of the paper, with a handle for moving saidcutting means into operative position.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to

be hereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts. throughout the several views, and in which Figure 1is an elevation of the device.

Figure 2 is aplan View thereof.

Figure-3 is an end view thereof.

Figure 4 is a section on fine 4-4 of Figure 2.

Figure 5 is a section on line 55 of Figure 4.

Figure 6 is an enlarged sectional view through the motor carrying end ofthe machine.

Figure 7 is a detail view showing a pair of the trimming knives.

In these views, the numeral 1 indicates an upright frame for supportingthe various parts of the device and 2 indicates a platform arranged atone side of the frame upon which the operator may stand. The uprights ofthe frame are provided with rollers 3 so that the device can be rolledfrom one place to another. I

A shaft A has its ends placed in the bayonet slots 5, one of the slotsbeing arranged in each side of the machine, this shaft being adapted tocarry the roll of wall paper which is indicated at A. A dis 6 isadjustably and removably arranged on the shaft through means of thecollar 7 which is held to the shaft by a set screw 8, a coil spring 9being placed on the shaft between the collar and disk so as to press thedisk against the roll of paper. This disk is used when a short roll ofpaper is placed on the shaft. The shaft is removably supported by theframe through means of the bayonet slots so that it can be lifted fromthe frame and a roll of paper placed thereon. A flat bar 10 extendsacross the frame in front of the roll of paper and forms a guide for thepaper leaving the roll.

A roller 11 is supported by pintles for rotary movement in the frame anda conveyor belt 12 passes over this roller. The belt also passes over aroller 13 arranged at the opposite end of the machine and idle rollers14- are placed intermediate the rollers 11 and '13, at the top of theframe, for supporting the upper reach of the belt. A belt tightener 15is pivoted to the top part of the frame adjacent the roller 13 and hasits roller 16 engaging the lower reach of the belt. A small roller 17formed .of metal, has its ends placed in the notches 18 formed in thesides of the frame and'acts topress the paper against that part of thebel top of the roller 11 so that the movement of the conveyor belt willact to draw the paper from the roll A.

A cylindrical casing 19 is supported in the frame adjacent the roller11, the lower part of the casing forming a paste chamber 20 which isprovided with a drain 21 in its bottom which is controlled by a valve22.

A brush roller B is rotatably mounted in the casing with the brushesarranged to dip into the paste in the paste chamber as the t passingover the roller revolves and the top part of the casing has an opening23 therein through which the paper is pressed against the bristles ofthe brushes by a roller 24;, preferably formed of wood and which has itspintles engaging the notches 25 formed in the sides of the frame. Idlerolls 26 are placed one on each side of the roller 24, over which thepaper passes as it enters and leaves the opening.

The brush roller is composed of the tubular sections 27, the outer onesof which are of larger diameter than the central one, the brushes 28which have socketed stems 29 on their inner faces engaging the sockets30 in the outer sections 27, the interiors of the stems being threadedfor engagement with the threadedstub shafts 31 journaled in the whichpasses through the sections 27, with one end projecting beyond a side ofthe frame to receive a handle 35. Thus by turning the shaft by means ofits handle, the brushes will be adjusted outwardly or inwardly, asdesired.

A shaft 36 extends across the frame with its ends journaled in the sidepieces thereof, said shaft being arranged between the brush roller andthe roll of paper. A pair of disk cutters 37 are fastened to this shaft,one adj acent each end thereof. A stub shaft 38 is 'ournaled in eachside piece of the frame under the shaft 36, and the inner end of saidstub shaft carries a disk cutter 39 which cooperates with the cutter 37to trim an edge 0 the paper. The rear end of the shaft 37 carries a gear40 which meshes with a gear 41 on the stub shaft 38 and a gear 42 isarran ed on the outer end of the other stub sha t and meshes with a gear43 on the front end of the shaft 36. A sprocket wheel 44 is arranged onone of the pintles of the brush roller B and a chain 45 passes over thissprocket wheel and over a small sprocket wheel 46 attached to the shaftof an electric motor M which is supported from the frame. An idle gear47 meshes with a pinion 48 attached to the pintle of the brush rolleradjacent the sprocket 44 and this gear 47' meshes with the gear 42. Thusthe cutters are rotated from the brush roller. An idle gear 49 mesheswith the pinion. 48 and with a gear 50 which is attached to one of thepintles of the roller 11 so that this roller 11 is also rotated from thebrush rpller.

A third cutter removably connected through the set screw 52 and a shaft53 having a plurality of annular grooves 54 therein is arranged underthe shaft 36 and is carried by the arms 54 which are pivotally connectedwith the sides of the frame, as shown in Fig. 6. A handle 56 is attachedto'one' ofthe arms for raising and lowering the shaft 53 to press thepaper against the cutter 51 which acts to reduce the width of the paper.projection 57 is attached to one of the arms and a stop 58 is providedfor enga ement by said-projection for limiting the ownward movement ofthe arms and the shaft 53.

From the foregoing it will be seen that as the paper is drawn off theroller A by the movement of the conveyor, between the cutter disks sothat its edges are trimmed and then it passes under the roller 24 whichpresses it against the rotating brushes, which act to coat the underface of the paper with paste. The paper then passes disk 51 isadjustably and with the shaft 36 upon the conveyor from which it can beWhen a picked up by the paperhanger. strip of paper of narrow width isneeded, the knife 51 is adjusted on the shaft 36 and then the handle ismoved. to raise the grooved roller 53, which will press the paperagainst it will first pass p the knife, it being understood that theknife will enter one of the grooves in the roller so that its cuttingedge is not dulled by coming in contact with the roller. The part of thestrip beingcut by the knife 51 which is not to be used, is not carriedthrough the pasting mechanism, but is allowed to drop from the roller53, as shown at a in Figure 6.

As willbe seen, all the movable parts are operated from the electricmotor and that any length of paper roller may be placed on the shaft 4by adjusting the disk 6 thereon or entirely removing said disk. It willalso be seen that the brushes can be easily adjusted outwardly when theybecome worn by turning the shaft 34 through'means of the handle 35. Thepaste chamber can be easily drained by opening the valve 22 and thenwater can be poured in the chamber to clean the same and the brushes andthen this water can be drained from the chamber by opening said valve22,

Figure 4' shows a block 59 extending across the frame adjacent theroller 11 and under which the belt passes, the paper being adapted topass over the block so that it can be cut by running a knife along thatpart of the paper resting on the block. The block is provided with agroove 60 to facilitate theknife cutting the paper.

It is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent.
